Accretion Product Formation from Self- and Cross-Reactions of RO2 Radicals in the Atmosphere.

Angewandte Chemie, 2018
Hydrocarbons are emitted into the Earth's atmosphere in very large quantities by human and biogenic activities. Their atmospheric oxidation processes almost exclusively yield RO2 radicals as reactive intermediates whose atmospheric fate is not yet fully ...

Accretion Product Formation from Ozonolysis and OH Radical Reaction of α-Pinene: Mechanistic Insight and the Influence of Isoprene and Ethylene.

Environmental Science and Technology, 2018
α-Pinene (C10H16) represents one of the most important biogenic emissions in the atmosphere. Its oxidation products can significantly contribute to the secondary organic aerosol (SOA) formation.

Forming Planets via Pebble Accretion

, 2017
The detection and characterization of large populations of pebbles in protoplanetary disks have motivated the study of pebble accretion as a driver of planetary growth.

The formation of Jupiter by hybrid pebble–planetesimal accretion

Nature Astronomy, 2018
The standard model for giant planet formation is based on the accretion of solids by a growing planetary embryo, followed by rapid gas accretion once the planet exceeds a so-called critical mass1.

Wind from the black-hole accretion disk driving a molecular outflow in an active galaxy

Nature, 2015
Powerful winds driven by active galactic nuclei are often thought to affect the evolution of both supermassive black holes and their host galaxies, quenching star formation and explaining the close relationship between black holes and galaxies.

Accretion Discs in Astrophysics

, 1981
If we put a particle in a circular orbit around a central gravitating body, it will stay in that orbit. If we then extract energy and angular momentum from the particle we may allow it to spiral slowly inwards.
